With respect to the drawings and the numerals of reference thereon, the car body of the invention includes longitudinally extending frame members I9 at the sides of said car body, and transversely extending frame members II at the ends of said car body. Each side frame member I 0 consists of a pair of elongated I-beams, denoted I2 and I3, respectively, having the body portions or webs Ill of said I-beams disposed vertically and'parallel with each other, and having the meeting edges of adjacent upper and lower anges, denoted I5 and I6, respectively, of said l-beams welded together, vas shown very clearly at Il. Portions of the meeting edges of the upper flanges I5 and the lower flanges I6 are cut away, and metal I8 to weld said flanges together is placed in said cut-away portions in any well known manner. Also at spaced apart intervals along the lengths of the side frame members I I), the connected I-beams are desirably reinforced by transverse webs I9 welded to the body portions orwebs I4 and to the flanges of said I-beams, as well as by U-bars 20 and filler bars 2| between adjacent body portions or webs I4, the U-bars and filler bars being shown as riveted to the body portions or Webs. The transverse webs I9, U-bars 29 and filler bars 2| could be attached to the I-beams in a manner different from that shown. Each end frame member II consists of an I-beam extending between the side frame members I0, there being an end frame member II adjacent each end of the car body in spaced relation to the outermost extremities of said side frame members I6. The end frame members IIy are perpendicular to the side frame members I0. The innermost upper and lower flanges, denoted 22 and 23, respectively, of the side frame members I9 detachably support, as by screw bolts 24, plates 25 at the inner sides of the upper and lower flanges, denoted 26 and 2l, respectively, of the opposite end portions of each end frame member II, and said plates 25 are welded to said upper and lower flanges 26 and 2l, as at 28. The end frame members or I-beams II are desirably reinforced by transverse Webs 29. Said end frame members or I-beams II are themselves interconnected by spaced apart` I-beams,

denoted 30 and 3|, respectively, extending length-v wise of the car body at opposite sides of the longitudinal center thereof. Opposite end portions ofthe upper and lower flanges of said I- beams 30 and 3| are ldetachably connected, as by screwboltsy 32, to adjacent flanges of the end` frame members or I-beams Il, the flanges v5, a plate 35 is |interposed between an upper flangev of each I-beam and the flanges upon the adjacent ends'of the I-beams 30` and 3|, and

said I-beams 30 and 3| are bolted as at 32 to Y.

said plates 35 as well as to the ;Ibeam`s I|. A pairof reinforcing plates, denoted 36 land 31, respectively, extend transversely ofthe car body at the' opposite* sides of the transverse center thereof, said plates 36 and 31 lying between Y the bodies or webs of the I-beams 30 and 3| and being welded or otherwise fastened to said I-beams 30 and 3|. As shown moreclearly in Figs. 1 and 6, four plates, each denotedl 38, are

bolted, as at 39, tol the'upper, outer flanges of the I-beams 30 and 3 I, said plates 38 being equally spaced from the vertical axis of the car body and at equal distances apart. Each'plate 38 is welded to a channel member 40, as at 4|, and each of the four channel members 40 extends horizontally outwardly toward a corner. of the car' body. A relativelyjshort I-beam 42 adjacent each corner of the car body'extends obllquely to the side and end frame'members I0 and desirably at a forty-five degree angle to each frame member. The I-beams 42 may include reinforcing webs 43. An end portion of each I-beam 42 is suitably welded to Van end frame member or `I-beam as at 44, and the'upper and lower flanges of the opposite .end portion of each I-beam 42 are Welded to the upper and lower plates 25,1as at 45. The body portion or web of each I-beam 42 is welded as at 46 to a vertical plate `41 which is detachably bolted, as at 48, to the body portion or web of the inner I- beam of each side frame member. Obviously, there are four vertical plates 41. In addition, there are four vertical `plates 49 bolted as kat 50 fto the body portion or web ofthe inner I- beam of each side frame member to which the opposite end portions of each end frame member orYI-beam are welded as at 5|. The outer ends of the channel members 40 are bolted as at 63 to plates 64 Welded to the I-beams 42.

Numeral 65 denotes axles for the car wheels 66, said axles being suitably mounted inthe body portions or webs of the I-beams of the side frame members as shown more clearly in Figs..1, 7 and 8. There are eight car wheels as shown, two at each corner of the car body. The car body may be self, or otherwise, propelled along the tracks 61. The car wheels may desirably be of width to about span' the space between thebody portions or Webs of the I beams of the side rframe members, as will be clear from Figs. 1

and '8, and the lower flanges of said I-beams of the side frame members are cut away, as denoted at 68, to accommodate the car wheels;

A bull gear 52 'is associated with the car body in novel and improved manner. Said bull gear may consist of an inner annular portion` 53 providingy an internal, vertically disposed gear sur` .face or toothed portion 54, an annular upstanding or vertical portion 55'providing an operating rail 56 of the bull gear adapted to constitute a lower rail for supporting a revolvable platform of anexcavating or other machine, and an annular horizontal portion or web 51 integrally connecting the'lower parts of the portions.` 53 and 55'. -The bottom surface of the horizontal portion or web 51 is flat. As disclosed, the bull gear consists of twoequal halves each extending y 180, and said halves of the bull gear are detachably connected'to each other by bolts 58 arranged inreinforcing flanges or webs 59 upon they different halves of said bull gear at the meeting ends ofthe two halves. cludes additional reinforcing flanges or webs 59 at spaced intervals about its periphery. `In practice, the bull., gear can, if desired, be cast as a continuous circumferential member. Preferably, however,vit'is when so cast cut to provide two diametrical halves detachably connectedin the manner as illustrated and described. d j f As shown vin the drawings, the bull gear is placed upon the car body so that the end portions of the detachably connected halves thereof lie directly over the'midlengths of the side frame members I0. When said bull gear lis upon the car body, the circumference of the horizon' tal portion or web 51 rests upon the upper flanges of the I-beams and 42, as well as upon the upper flanges of the I-beamsflZ and I3; that is,

upon the side frame members I0. 'Ihe bull gear is desirably welded, as at 60,' to the upperflanges of the I-beams and is welded, as at 6|', to.

the upper flanges of the I-beams 42. Also, the bull gear is desirably bolted, as at 62, to the side frame members l0 and end frame members The bull gear in-L It will be evident from the drawings and the4 above description that the assembly includingthe car body and the bull gear is detachable into a plurality'of separate units of said carV body,

which separate units are, each of the side frame .closure as made,-the plates 36 are integralwith the channel members 40, the plates 25 are integral with the I-beams and 42, the vplates 64 and 41 are integral with said I-beams 42, `and the plates 49 are integral with the I-beams The several units constituting the car body and the'bull gear can` be transported Vin knocked down condition and assembled at the location where an excavating machine -having the car body and, bull gear is `to flnd use, as will be understood. Of course, the several units of the car body and the bull gear can be independently constructed when the machine is being manufactured, to` beafterwards assembled together and connected in the manner as set forth. That is to say, while theV description as given follows a general sequence to produce the car body with bull gear, this sequence can be altered. For example, the two diametrical halves ofthe bull gear could be welded to the I-beams and 42 either before or after said I-beams are welded to `each other and while disassembled from the side frame members |6. 'Also, the structure including the I-beams 30 and 3| can be assembled with the I-beams either before .or alterthe` aoeaaso sideframe members Ill and end frame members or I-beams -Ii are assembled.' And the channels 40 canbe assembled into the structure during any preferred stage of its manufacture, What is meant is, that the units of the car body with bull gear as illustrated and described are not only separate units, but are as well units which can be independently made and, speaking generally, independently assembled together.

A platform (not shown) is adapted to berevolvably supported upon the car body through the instrumentality of a king pin 69, the operative rail 56 of the bull gear 52, an upper rail (not shown) on the platform, and rollers or Wheels of a container ring (not shown) between said operative rail and upper rail. The king pin 69 is bolted as at 39tothe upper flanges of the I-beams 30 and 3| and. extends vertically upward.l Said king'pin may additionally be welded to said I-beams 3B and 3i, as well as to the reinforcing plates 36 Iand 31. The lower portion of the king pin is of rectilinear conformation, and the upper portion thereof is of reduced, cylindrical shape. The king pin is directly above the longitudinal andtransverse center of the car body yas disclosed. The revolvable platform will include a bearing portion, arranged concentric to the upper rail, adapted to receive the king pin, said bearing portion also being concentric to the operative rail 56 ofthe bull gear 52, ar-

ranged directly below the upper rail. The container ring with rollers or wheels will lie between said operative rail and upper rail.

Means for revolving the platform in either direction may include a pinion l0 meshing With the gear surface lor toothed portion 54, a vertical shaft 'H ilxedly carrying the pinion, and means (not shown), desirably on the platform, for supporting and rotating said shaft.
